Major cation Mg²⁺ was presented in enamel as major substituted species. The quantity of Mg and the Mg isotopic ratio in tooth can provide information on the environment, dietary habits, and oral health of individuals. As a result, a method was developed for the determination of Mg isotope based on high-precision multiple collector-inductively coupled plasma-mass spectrometry (MC-ICP-MS). The samples were dissolved using a microwave digestion system. Separation of Mg was achieved by cation exchange chromatography of AG50W-X8. The sample solutions were loaded on the resin with 1 mol/L HNO₃, the other ions such as Na⁺ were eluted with 40 mL of HNO₃ (1 mol/L), and then the Mg was eluted with 30 mL of HNO₃ (1 mol/L), finally the resin was washed with 60 mL of HNO₃ (1 mol/L). The Mg isotope was measured using multiple collector-inductively coupled plasma-mass spectrometry (MC-ICP-MS). The "sample-standard" bracketing technique was used to correct the instrumental mass bias. The results show that the fast and effective method can be used for the separation, pre-concentration and determination of Mg isotope in calcium-rich tooth samples. Giving values of ²⁶Mg were from -1.38‰ to 4.59‰. The established method for Mg isotope determination provides an important scientific basis for ancient population migration, ancient diet analysis and disease by Mg isotope of ancient human teeth.
